The slide on , lockable base that comes with an I Pilot can be drilled to fit most previous holes.
With the bass boats and their TM's, the holes are close to two/three feet in total length and the MK's base plate are only 14" in length so you could still have two sets of holes showing. You can note in my video that the base can be slid back to keep it from hanging over when launching or trailering. Another big plus.
